Education and Training
Vasken Dilsizian, MD, has been a professor of radiology and medicine at the University of Maryland School of Medicine since 2001, and chief of the division of nuclear medicine at the University of Maryland Medical Center in Baltimore since 2007.
He graduated from Tufts University School of Medicine in 1982. This was followed by Internal Medicine residency at Georgetown University School of Medicine in 1985, Fellowship in Cardiology at Boston University Medical Center and Massachusetts General Hospitals in 1988, and Nuclear Medicine residency at the National Institutes of Health in 1992. He holds a master's (Tau Beta Pi) and bachelor's (Magna Cum Laude) degree in chemical engineering, both from Tufts University. He is a Diplomate of the American Board of Internal Medicine, Cardiovascular Diseases, and Nuclear Medicine.
Dilsizian has been involved in many councils, committees, and task forces of the American College of Cardiology, American Heart Association, American Society of Nuclear Cardiology (ASNC) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI). He was elected as the President of the SNMMI (2019-2020) and currently serving on the Board of Directors as the immediate past president (2020-2021). He served as the President of the Cardiovascular Council of the SNMMI (2013-2014) and was awarded the 2014 Hermann Blumgart Award for his innumerable contributions to the science of nuclear cardiology. He was the SNMMI Henry N. Wagner, Jr. Cardiovascular Nuclear and Molecular Imaging Lecturer in 2014 and 2015. He is on the Board of Directors of ASNC, and was the Program Chair of the ASNC 2014 Scientific Sessions. In 2016, he was bestowed as “Master” of American Society of Nuclear Cardiology (MASNC) for his contribution to the field of nuclear cardiology and for holding senior leadership positions within the Society. He serves as the Chair of the ACC Task Force on clinical competence and training in nuclear cardiology (COCATS 4 – TF6), Board of Scientific Counselors of the National Institutes of Health, Clinical Center (2018-2022), and the Vice Chairman of the Nuclear Regulatory Commission (NRC) Advisory Committee on the Medical Uses of Isotopes (ACMUI; 2021-2022).
He spent 13 years at the National Institutes of Health, where he served as the Director of Nuclear Cardiology from 1992 to 2001. His research efforts over the past 35 years have culminated into over 260 original, peer-reviewed manuscripts and invited editorials/articles, 10 books, and 50 book chapters. He has served as a Guest Editor on 5 periodicals and excerpts. He serves as the Deputy Editor of the Journal of American College of Cardiology - Cardiovascular Imaging, Section Editor of the Journal of the American College of Cardiology, and Section Editor of Current Cardiology Reports. He is a co-editor of the “Atlas of Nuclear Cardiology” (now in its 5th edition), “Cardiac CT, PET and MR” (now in its 3rd edition), and the “Atlas of Cardiac Innervation”. He is also a co-author of the “Nuclear Cardiology” chapter in Braunwald’s Heart Disease: A Textbook of Cardiovascular Medicine (2005-2018).
